What’s the best way to paint an interior door? Text

First, select a durable, scrub-able paint. Your family handles the doors much more often than the walls.
Many homeowners choose a semi-gloss paint for the doors because it’s extra-durable, but many of the newer flat paints are formulated for high-traffic areas and are as easy to clean as traditionally glossy paints. In fact, high-gloss is no longer the paint of choice for doors and wet rooms like kitchens; consider using a semi-gloss or satin finish instead for a cleaner, more updated look.
Next, take the door off the hinges and lay it flat on the ground or on a pair of saw horses. If you’re painting indoors, lay a plastic tarp on the floor, across the whole room, not just under the door. Paint splatters! Paint one side, let it dry for 24 hours, and turn it over to paint the other side. If you don’t want to remove the door, you can tape the hinges and either remove or tape door knobs and other metal with blue painter’s tape to protect them from splatters.  

Either way, if the door has raised panels, paint the panels first. Then paint the horizontal sections of the door, and finally, paint the vertical sections.   Paint the outer edges of the door the same color as the room they’ll open into. That means one edge might need a different color from the other because if the door opens into the bedroom, the outer edge will show on the hallway side and should match the color of the hallway.
